Mosquito lamp power supply scheme, 220v to 12v chip, AC drive a 140MA fan and a 90MA LED lamp
The working principle of the electronic mosquito killer lamp is to use the phototaxis of the mosquitoes to attract the mosquitoes to make them electrocuted. The high-efficiency mosquito lamp is used to attract mosquitoes and other harmful flying insects. It can kill the fly instantly by electrostatic shock Insect; electronic mosquito killer lamp circuit design current limit, low power consumption, high efficiency, as long as it is connected to the power supply can be used without any chemical substances volatilization. The airflow suction mosquito lamp is equipped with a fan, which absorbs the mosquitoes through the airflow, causing death. The airflow mosquito-absorbing lamp is small in size and can be carried around, and is generally used in homes.
So what is the power supply for the mosquito killer lamp? The mosquito killer lamp is usually a 12V or 5v working fan, and a blue LED lamp. By changing the 220V AC to 12V or 5V DC, the common way is The disadvantage of using a resistance-capacitance buck circuit is that the heat generation is greater than the EMC. The advantage is cheap; in addition, it uses a non-isolated chip, which can be converted into a 12V or 5V DC voltage through the chip circuit after direct AC 220V rectification, driving a 140MA or so Fan and a 90MA LED light.
Mosquito lamp power supply scheme, 220v conversion 12v chip, wide voltage input 45v-265v, with over temperature protection, over current protection, short circuit protection, the maximum current output can reach 1A, can adjust the current through cs current limiting resistor, ripple small work Low energy consumption has passed European regulations and American regulations.
